Can't think.

of polygon you're trying to draw. (It seems that you're trying to draw an arbitrary one and just assuming that the line segments you're drawing will close at the end.) You use a variable t3% before defining it, only updating it after you use it the first time. (You may simply be assuming that t3% starts out at zero. Assuming that non-explicitly initialized variables have a zero value is sloppy programming and can be quite dangerous.) Using integer angles seems dangerous. That may relate to your apparent assumption that your polygon ends up closed.

Glenn, all polygons end up closed.
It's a perfect polygon that should maintain the appropriate width to height ratio and then be slanted.

Are you looking for this?

Hey, GREAT! Thanks. THe rotation is good, but what I really want is slant, like the italics are doing. Since the polygons will be drawn on a 2:1 isometric surface, I want them to be flat, not stand.

isn't the issue. The issue is what your code actually draws. QB doesn't know math. That's *your* job.

I know. But integers are good enough in this case.

If they're what's making your code not work, they aren't. It seems that the code Antoni posted that seemed to work for you used values of t3 that weren't of INTEGER type.

You're right, decimals are required. However, my code had a different formula for t2, too.
